Productivity and adaptability of the new carrot and garlic cultivars in Lithuania



The new carrot (Daucus sativus Röhl.) hybrids ‘Ieva’ and ‘Rokita’ and the garlic (Allium sativum L.) cultivar ‘Dangiai’ were developed at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry during 2012–2015. The breeding direction was to increase vegetable production and to improve its quality. Carrot roots of the new hybrids have good properties for storage and maintenance of biochemical components. The hybrids ‘Ieva’ and ‘Rokita’ were compared with three foreign hybrids ‘Jitka’, ‘Maestro’ and ‘Champion’. Lithuanian hybrids were distinguished by the highest marketable yield ranging from 64.6 to 66.7 t ha-1. The hybrid ‘Ieva’ accumulated the highest content of carotene 21.8 mg 100 g-1, total sugar 8.6% and dry soluble solids 11.5%. Roots of the hybrid ‘Rokita’ were the most resistant to black rot of carrots and bacterial soft rots. Good adaptability, productivity and a stable number of cloves per bulb is characteristic of the new garlic cultivar ‘Dangiai’. The overwinter survival rate of plants was 98%, the productivity – 14.6 t ha-1 and the average weight per bulb – 75 g.

The carrot hybrids ‘Ieva’ and ‘Rokita’ and the garlic cultivar ‘Dangiai’ have been included in the National Plant Variety List and in the EC Common Catalogue of Varieties of Vegetable Species.
